What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world.
That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and
voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted
to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning,
there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

» The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.

» If you wish to use your user account, you will probably need to reset your password.

Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Use the command line to log into Dropbox. You have to replace [email protected] with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag.

This commands queries the delicious api then runs the xml through xml2, grabs the urls cuts out the first two columns, passes through uniq to remove duplicates if any, and then goes into linkchecker who checks the links. the links go the blacklist in ~/.linkchecker/blacklist. please see the manual pages for further info peeps. I took me a few days to figure this one out. I how you enjoy it. Also don't run these api more then once a few seconds you can get banned by delicious see their site for info. ~updated for no recursive

With the "--resolve" switch, you can avoid doing DNS lookups or edit the /etc/hosts file, by providing the IP address for a domain directly. Useful if you have many servers with different IP addresses behind a load balancer. Of course, you would loop it:

This relies on a public API from http://longurl.org. So, this has the weakness that if the service disappears, the function will break. However, it has the advantage that the shortened URL service will not be tracking your IP address and other metrics, but instead will track longurl.org. Thus, you can remain anonymous from the shortened URL services (although not anonymous from longurl.org). It does no sanity checking that you have provided an argument. If you do not provide one, "message" is displayed to STDOUT.
